Advantages of friction
- Friction helps in everyday activities like walking, driving, and writing.
- Shoes, car tires, brakes, and writing tools are examples where friction is essential for safe and effective use.
- Friction generates heat efficiently for starting fires.
- Handheld tools and utensils maintain grip with the help of friction.
- Exercise equipment like treadmills experience resistance due to friction.
- Musical instruments like violins require friction for operation.
- Friction enables safe climbing and descending on rough terrains.
Disadvantages of friction
- Friction wears and tears on moving parts.
- It generates unwanted heat and reduces energy efficiency.
- Friction also increases fuel consumption in vehicles.
- It creates resistance and makes movement harder.
- Friction can cause noise and vibrations in machinery.
- It requires frequent maintenance and lubrication.
